It's an oversight that these weren't already checked, and probably they
are all latent bugs.

This is the kind of thing the safety API prevents, but (1) that's mostly
on hold pending Longo's work; and (2) we aren't really ready to switch
over the event stuff fully anyway (or at least for me it's one of the
last things to do).
